The latest version of Zeus adds a $MEX macro tag which allows the creation of a tag value based on the results of a macro script.

This macro execute tag can be used in this basic format:

Code: Select all

$MEX<macro_script>

Alternatively, the tag can be used in this arguments format:

Code: Select all

$MEX<macro_script arguments>

The macro_script represents the name of the script to be run and the arguments represent space delimited argument values passed to the macro.

Here is an example of a typical script:

Code: Select all

function key_macro()
    local arguments = "";

    local count = argc();

    if count > 0 then
        count = count - 1;
        for i = 0, count, 1 do
            arguments = arguments .. argv(i)
            arguments = arguments .. ' '
        end
    end

    local message = "This output generated was by the 'mex-test.lua' macro."

    if (string.len(arguments) > 0) then
         message = message .. " Arguments Supplied: " .. arguments
    end

    -- this will be the result of the macro expansion
    print(message)
end

key_macro() -- run the macro

This actual macro comes as part of the latest installation and can be found in the Zeus zScript folder in the mex-test.lua file.

Here is an example of how this macro script can be used using the basic format:

Code: Select all

$MEX<mex-test.lua>

Here is an example of how this macro script can be used using the arguments format:

Code: Select all

$MEX<mex-test.lua arg1 arg2 arg3>

To see how these work, use the Tools, DOS Command Line menu and run this echo command:

Code: Select all

echo $MEX<mex-test.lua>

That will result in the following output:

Code: Select all

This output generated was by the 'mex-test.lua' macro.

And when this command is run:

Code: Select all

echo $MEX<mex-test.lua arg1 arg2 arg3>

That will result in the following output:

Code: Select all

This output generated was by the 'mex-test.lua' macro. Arguments Supplied: arg1 arg2 arg3

Another example is the mex-dir.py macro, which lists the files in a folder based on file filter.

For example, this echo will list all text files in the current directory:

Code: Select all

echo $MEX<mex-dir.py *.txt>

This echo example lists all text files in the c:\temp directory:

Code: Select all

echo $MEX<mex-dir.py c:\temp\ *.txt>
